The collection of essays in this festschrift celebrates the extraordinary scholarship of Professor Piriya Krairiksh, the distinguished Thai art historian on the occasion of his 80th birthday. The collection was seen as the most fitting way to honour an esteemed mentor and colleague, who has dedicated his life to teaching and fundamental research on Thai and Southeast Asian art and archaeology is to support further scholarship and debate on the issues in these fields. The volume gathers together contributions from many of his colleagues, friends, students, disciples, and admirers in tribute to his gift to the world of his scholarship.
